"body" configuration option without "Subject" header?
Hi,
the Mail::Spamassassin::Conf manpage says that the "body" rule also
contains the "Subject" header as first part of the body content. I'm
trying to create a rule that catches empty messages but if the Subject
is always prepended, I can't do that. Is there a way to get the text or
html parts of the message alone, without any headers that I can also
check otherwise?
Using SA 3.1.8 on Linux.

fwiw, I was thinking of the rendered part when I wrote that, it obviously
doesn't do anything for rawbody/HTML.

^\s*$ ?
You're going down the slippery slope, btw. Originally, there was nothing
in the body, so rawbody is fine. If there is now html w/ just a space,
the next step will be random crap plus the pdf, so I wouldn't waste my
time on this and just target other information in the mail.
ymmv.

Okay, and what about an HTML part like this:
<html>
<head>
<some garbage here>
</head>
<body><p> </p></body>
</html>
I consider this empty, but ^$ does not. Any suggestions?

You want empty body other than the subject line? I think there is an
EMPTY_BODY rule already, or something very similar to that. Also I believe
rules that fire on various amounts of body text.
However, you could probably do something like the following. This is
UNTESTED, and I may have the /m and /s options wrong to make it really work
correctly. But possibly something along the lines:
body EMPTYNESS /^Subject[^\n]{0,150}[\n\s]{1,500}$/im

Hm, according to the manpage, this doesn't remove HTML tags and it's
matched line by line, so checking for a visually empty message isn't an
easy job here. I guess for such advanced tests like whether a message is
empty or not, I'll need to learn Perl and create my own function (or
plugin) for it. :(
Or has anybody a quick measure agains empty mails with "Invoice #0000"
in the subject and only a PDF attached?
